There has been a significant increase in the proliferation and implementation of Wireless Sensor Networks (WSNs) in different disciplines, including the monitoring of maritime environments, healthcare systems, and industrial sectors. It has now become critical to address the security issues of data communication while considering sensor node constraints. There are many proposed schemes, including the scheme being proposed in this paper, to ensure that there is a high level of security in WSNs. This paper presents a symmetric security scheme for a maritime coastal environment monitoring WSN. The scheme provides security for travelling packets via individually encrypted links between authenticated neighbors, thus avoiding a reiteration of a global rekeying process. Furthermore, this scheme proposes a dynamic update key based on a trusted node configuration, called a leader node, which works as a trusted third party. The technique has been implemented in real time on a Waspmote test bed sensor platform and the results from both field testing and indoor bench testing environments are discussed in this paper.
无线传感器网络（WSN）在包括海洋环境监测、医疗系统和工业部门在内的不同学科中的应用和实施显著增加。在考虑传感器节点约束的同时，解决数据通信的安全问题变得至关重要。为确保无线传感器网络具有高度安全性，人们提出了许多方案，包括本文所提出的方案。本文提出了一种用于沿海海洋环境监测无线传感器网络的对称安全方案。该方案通过在经过认证的邻居之间的单独加密链路为传输数据包提供安全性，从而避免了全局重新密钥化过程的重复。此外，该方案基于一种称为领导者节点的可信节点配置提出了一种动态更新密钥，该领导者节点充当可信第三方。该技术已在Waspmote测试平台传感器上实时实现，本文讨论了现场测试和室内台架测试环境的结果。
